Most of those files are not temporary files, but cached files. The error you reported only occurs when a required file does not already exist in the cache, and like you said, it appears to be the case that two jobs are trying to add the same file to the cache at the same time, and one job is failing because the other deletes a temporary file that is being used by both. I guess. > Here are the error messages that are occuring now: > > Traceback (most recent call last): > File > "/home/spxiwh/ihope/852450000-852700000/nsbhinj_summary_plots/../executable >s/plotinspmissed", line 625, in ? > savePlot( opts, filename, titleText) > File > "/home/spxiwh/ihope/852450000-852700000/nsbhinj_summary_plots/../executable >s/plotinspmissed", line 108, in savePlot > dpi_thumb=opts.figure_resolution) > File > "/home/spxiwh/lscsoft/executables/cbc_s5_1yr_20070129/pylal//lib64/python2. >4/site-packages/pylal/InspiralUtils.py", line 54, in savefig_pylal > fig.savefig(filename, dpi=dpi) > File "/home/spxiwh/test/matplotlib/figure.py", line 682, in savefig > self.canvas.print_figure(*args, **kwargs) > File "/home/spxiwh/test/matplotlib/backends/backend_agg.py", line 456, in > print_figure > self.draw() > File "/home/spxiwh/test/matplotlib/backends/backend_agg.py", line 392, in > draw > self.figure.draw(renderer) > File "/home/spxiwh/test/matplotlib/figure.py", line 544, in draw > for a in self.axes: a.draw(renderer) > File "/home/spxiwh/test/matplotlib/axes.py", line 1063, in draw > a.draw(renderer) > File "/home/spxiwh/test/matplotlib/axis.py", line 595, in draw > self.label.draw(renderer) > File "/home/spxiwh/test/matplotlib/text.py", line 340, in draw > bbox, info = self._get_layout(renderer) > File "/home/spxiwh/test/matplotlib/text.py", line 187, in _get_layout > w,h = renderer.get_text_width_height( > File "/home/spxiwh/test/matplotlib/backends/backend_agg.py", line 240, in > get_text_width_height > Z = texmanager.get_rgba(s, size, self.dpi.get(), rgb) > File "/home/spxiwh/test/matplotlib/texmanager.py", line 334, in get_rgba > pngfile = self.make_png(tex, fontsize, dpi, force=False) > File "/home/spxiwh/test/matplotlib/texmanager.py", line 255, in make_png > fh = file(outfile) > IOError: [Errno 2] No such file or directory: > '/home/spxiwh/.matplotlib/tex.cache/fb2014e54961855bd04020b61190867c.output >' That doesnt make any sense to me. file defaults to open a file in append mode, it doesnt matter if a file exists or not. Maybe you could try to figure out why that fails and report back. > And once I noticed: > > Traceback (most recent call last): > File > "/home/spxiwh/ihope/852450000-852700000/allinj_summary_plots/../executables >/plotinspmissed", line 661, in ? > dpi_thumb=opts.figure_resolution) > File > "/home/spxiwh/lscsoft/executables/cbc_s5_1yr_20070129/pylal//lib64/python2. >4/site-packages/pylal/InspiralUtils.py", line 54, in savefig_pylal > fig.savefig(filename, dpi=dpi) > File "/usr/lib64/python2.4/site-packages/matplotlib/figure.py", line 682, > in savefig > self.canvas.print_figure(*args, **kwargs) > File > "/usr/lib64/python2.4/site-packages/matplotlib/backends/backend_agg.py", > line 456, in print_figure > self.draw() > File > "/usr/lib64/python2.4/site-packages/matplotlib/backends/backend_agg.py", > line 392, in draw > self.figure.draw(renderer) > File "/usr/lib64/python2.4/site-packages/matplotlib/figure.py", line 544, > in draw > for a in self.axes: a.draw(renderer) > File "/usr/lib64/python2.4/site-packages/matplotlib/axes.py", line 1063, > in draw > a.draw(renderer) > File "/usr/lib64/python2.4/site-packages/matplotlib/text.py", line 340, > in draw > bbox, info = self._get_layout(renderer) > File "/usr/lib64/python2.4/site-packages/matplotlib/text.py", line 187, > in _get_layout > w,h = renderer.get_text_width_height( > File > "/usr/lib64/python2.4/site-packages/matplotlib/backends/backend_agg.py", > line 240, in get_text_width_height > Z = texmanager.get_rgba(s, size, self.dpi.get(), rgb) > File "/usr/lib64/python2.4/site-packages/matplotlib/texmanager.py", line > 330, in get_rgba > X = readpng(os.path.join(self.texcache, pngfile)) > RuntimeError: _image_module::readpng: file not recognized as a PNG file No idea, sorry.
